Meant to reply to the message above

From native code I somehow have to supply the correct MethodInfo when calling a generic and I have never understood how to generate that 😅

[polar acorn]

Native code

grandpa_simpson_hat_rack.gif

[wintry quarry]

They say the exponent in decimal is a "decimal number". I don't understand how they store that or how they do math with it on a binary computer

[restive lantern]

Anyways guess I'm doing a type lookup then.

[wintry quarry]

Huh

[slender nymph]

they're using it from native code for whatever reason

[polar acorn]

Can't post reaction gifs here so just plug the name into gif search. I ain't touching native code with a ten-foot-pole

[naive pawn]

ieee 754 binary floats store a sign s, mantissa m, and exponent e to represent a value of s*1.m*2^e
decimal uses m * 10^e instead

[wintry quarry]

Alright but your CPU has operations defined for doing math with ieee 754 floats how do they do math for this

[restive lantern]

I'm programming a mod that is supposed to work for all Unity games to use Steam Audio with reflection using collision data by overriding AudioSource 🙃
I could use C# for this, but then it wouldn't work with games compiled for il2cpp.
Maybe there is a better way to do this, but my current way is to just do everything on the native side of things.

[slender nymph]

congrats, your questions are off topic! modding discussions are not permitted here

[restive lantern]

Just wanted to explain. No further discussion.

[polar acorn]

At least it's not fuckin gorilla tag

[naive pawn]

manually

[restive lantern]

Lol...

[wintry quarry]

So if they're doing the math in software doesn't that make decimal like thousands of times slower than regular floating point math?

[slender nymph]

the reason they are not permitted here is because you have to do things in non-standard ways, like calling FindObjectByType in native code. it isn't just about mentioning modding that is not permitted.
#1201856945791705108 message

[naive pawn]

eh, not really. a few extra machine cycles.

they still are simple operations

[restive lantern]

You have linked a channel inaccessible to me.

About software maths, there are CPUs that can only do software floating point and there definitely is a pretty significant difference in performance...

[slender nymph]

i don't see what that second point has anything to do with anything i have said. that is a separate discussion which i have not participated in.

[polar acorn]

#1161868835423526933 should be accessible to everyone

[slender nymph]

as for what i linked, it was a mod explaining why modding discussions are not permitted in this server because "The types of conversations modders have are often non-standard, often it's discovered someone's modding because they cannot do simple debugging or necessary basics, because they usually have access to an extremely limited subset of the engine."

[naive pawn]

it's not inaccessible; it's just not loaded. try clicking it

[polar acorn]

The mods response on modding discussion from the linked thread:

[restive lantern]

I was referring to the other ongoing topic, I just dislike putting things in separate messages to reduce pings in DMs. Just a habit.

[restive lantern]

Ohhhh yeah now I can see it, thanks!

[naive pawn]

(tip: you can reply without pinging, shift click the reply button or disable mention on the "replying to" banner)

[polar acorn]

At this point it's mostly in the case of "You aren't going to find much help for calling these functions from native code since it's not something most people have to do so we don't really have experience with it".

[restive lantern]

Oh yeah I know, but I used to send lots of separate messages in DMs that generate pings regardless, and people got annoyed so I developed the habit to combine multiple messages in one 😅

[polar acorn]

You might have to do some documentation binging on your own

[restive lantern]

Thank you, anyways

[grim marsh]

Hello, I have a problem with a raycast and maybe somehere could help me fix it?

Basically I have a script that shots the ray and returns hit game object, but the moment there is no object (player looks into sky and shots ray) it returns null and I get a bug report that no object is set to variable. Any ideas how I can fix it/bypass it

[naive pawn]

about this; floating-point is slow in general (compared to fixed point), yes, but decimal floating point would likely not be much slower than ieee 754 hardware floating-point
they're similar complexities

[grim marsh]

Or maybe a tutorial that could help me fix it

[polar acorn]

You should check if your raycast hits anything before attempting to do any code with it

Usually by wrapping it in an if

[grim marsh]

It is in if

[polar acorn]

Show !code, and the error you're getting

Are there any metrics on how many cycles modern CPUs need to do floating point maths? Or does that depend on the values that are being worked with?

[naive pawn]

no clue tbh

probably googlable

[verbal dome]

I see some charts pop up every now and then

[restive lantern]

I have implemented fixed point maths (because I have no idea about floating point) in hardware before, it did work in a single cycle but ate sooooo damn much space 😅 no wonder CPUs nowadays have so many transistors.

[restive lantern]

I have developed a certain distrust in Google for such things, ran into AI generated shit way too often by now 😦

[rich adder]

You can omit AI crap

[restive lantern]

Please tell me, how? 😮

[rich adder]

forgot the link params but you can easily just click here

[restive lantern]

I remember attempting to research something and all Google gave me was the same AI generated article in like 20 languages lol

[restive lantern]

Oh wow... why's that not the default?

[verbal dome]

Funny how "web" isn't the default for a search engine anymore

[polar acorn]

Easier way: include swearing in your search.

"Picture of an owl" -> AI crap
"Picture of a FUCKING owl" -> Only human made

[rich adder]

cause AI crap 📈 🤑

[naive pawn]

or filter for stuff before 2020 or smth

[restive lantern]

That worked for a while but then articles claiming to be from before 2020 popped up that were definitely AI generated lol

[rich adder]

all that stuff is still all in the LLMs no ?

[slender nymph]

too bad google is currently planning on adding ai bullshit to this too. i recently got one of their opinion rewards surveys about what kind of AI bullshit i wouldn't mind seeing in that view

[rich adder]

shiit.. someone needs to make a google search that omits that crap..

[ripe shard]

we need AI to remove AI

[restive lantern]

There are models that detect AI generated text, but that's probably way to slow to run for each search result

[ripe shard]

its somewhat fascinating how 'everyone' invests in AI that nobody actually wants.

[polar acorn]

There's no money in not pushing for techbro VC buzzwords

[restive lantern]

Yeah..

[polar acorn]

Venture capital is a sickness

[eternal needle]

and those are all mostly crap

[restive lantern]

Oh well

[ripe shard]

i feel like the world is more and more made for those 0.5% of people who are suckers for that kind of exploitative marketing BS and the rest of the world has to run along.

[polar acorn]

I have heard they're quite good at identifying autism. Likely better at that than identifying AI

[restive lantern]

We need something like an adblocker, but for AI. A list of websites that contain AI shit and that are then automatically blocked.

[ripe shard]

by now that would basically mean turning off your PC

[restive lantern]

True 🤦‍♂️

[ripe shard]

also not all AI is bad, i like my intellisense

[eternal needle]

😔 i dont seem to have this option, ive been searching every so often and the latest way to remove it was google labs. When i went there, the site isnt even set up yet!

[naive pawn]

gentle reminder, this is kinda way off topic

[rich adder]

to call it "Intelligence" is being generous

[restive lantern]

Sure there are awesome uses, but talking about AI shit specifically.

We somehow drifted from floating point to AI

[ripe shard]

not really, its actually accurate, if you read it in the "CIA" sense of intelligence

[restive lantern]

What off-topic channels are here?

[rich adder]

none

[polar acorn]

There aren't any

[ripe shard]

well, AI is a network of floats

[restive lantern]

Oh well lol

[ripe shard]

imagine replacing discord mods with some AI

[rich adder]

Image unity documentation one day just says Unity Muse as default search

[ripe shard]

What about #763495187787677691?

[polar acorn]

Yep, just saw right as I sent

[grim marsh]

Wrong key

[polar acorn]

So, what's the error you're getting?

[grim marsh]

It returns null when I use it and ray doesn't hit anything

"Object reference not set to an instance of an object"

[polar acorn]

What line

[grim marsh]

second if

[polar acorn]

Ah, because you don't actually have anything in your if statement

Take a look at the first if statement. Compare it to your second.

Notably, the ends of the lines

[rich adder]

when we open a if statement block, you probably don't want to end it before doing anything inside of it lol

; means "end this statement"

[grim marsh]

Isn't the second one nested in the first if?

[rich adder]

You close the first if before doing anything else

[polar acorn]

The first if contains nothing

An if statement runs until it finds either a { or a ;, whichever comes first

[grim marsh]

Doesn't it run everyithing in { }?

I'm confused now

[rich adder]

not if you end it first with ; like digi mentioned

[grim marsh]

Oh I see it now

[polar acorn]

It does. If it gets to the { before it ends

But yours does not

[grim marsh]

There is this one ; after if💀

😭

Thank you guys

[naive pawn]

it runs the statement that follows the if
{ ... } is a block statement that holds other statements
; is an empty statement that does nothing

[grim marsh]

traitor

[naive pawn]

so if you have if (...) doThing();, it runs only doThing()
if you have if (...) { ... }, it runs the entire block statement
if you have if (...);, it runs the empty statement which does nothing

if you have if (...); {} like here, the if runs the empty statement, then the block statement runs detached from the if

are you trying to search through code? if not, you're in the wrong place

[rich adder]

probably want to use the included Search

Window -> Search -> New Window

[naive pawn]

you're just asking about using the editor, that would probably just go in #💻┃unity-talk

[grim marsh]

Yeah ik I just didn't saw this one ; that I put here accidentally

[queen adder]

how long does it take to get good enough to do this? : https://www.youtube.com/watch?v=4O0_-1NaWnY

[naive pawn]

very

also not really a relevant question to learning

you shouldn't set "make thing fast" as a goal

just "make thing" is already a significant goal

[restive lantern]

Specially without a game engine, though most game engines don't handle voxel graphics very well.

[naive pawn]

imposing a time limit on yourself when you're still a beginner will only stress you out and make you dislike the experience

[restive lantern]

Time limits are great if you know you can do something but want a bit of an extra challenge, as Chris pointed out it's bad if you just want to learn.

[rich adder]

years

[queen adder]

i want to get good at coding

[rich adder]

If you commit yourself you will get good

[queen adder]

english isnt language

[restive lantern]

Coding has many facettes, you can't be just "good at coding", there are so many subcategories.

[naive pawn]

don't worry about "getting good"
that's a moving goal
set a solid goal for yourself, like making a project

[restive lantern]

You'll never feel like you're really good at coding because coding is just such a huge space there's always more to explore.

if it could... do you think dyno would be running a whole instance of unity editor

[queen adder]

I am learning react native. I wont work for coding but will enjoy making things for myself and community

[polar acorn]

It doesn't run anything it just brings up a bot showing how to post code

[proper hawk]

ohh

makes sense

saw bots that can run basic stuff

[restive lantern]

Imagine you could just make that bot execute arbitrary code lol

[naive pawn]

there are bots that can

[slender nymph]

there are repl bots, but dyno is not one of them

[naive pawn]

but you wouldn't be able to run unity library code in them

[restive lantern]

There'd be way too many bitcoin miners in that bot by now if you could just run code without restrictions

[naive pawn]

("i run code" that uses piston)

[naive pawn]

i don't think most public use repls have internet access

[restive lantern]

You'd hope so

[naive pawn]

the contained ones anyways. something like replit obviously does

[restive lantern]

Heck people have abused GitHubs actions system to run miners before

I've seen bots made by inexperienced people that had a "calc" command that literally just pushed everything into eval() 💀

[rich adder]

I wonder if you can do something interesting with using Unity as a plugin..

idk how much Unity API Code it can run as plugin mode
https://docs.unity3d.com/Manual/UnityasaLibrary.html

[restive lantern]

Literally everything, if you know the APIs. It would certainly be possible.

[inland latch]

hi not sure if this'd go here ot not since it's about the editor not coding, but for some reason my unity editor keeps making a really subtle static noise, and i know it's unity as when i close unity it stops, and when i mute the unity application in sound mixer it also stops. the sound is coming through my speakers so it's not a hardware thing, if it was i don't think muting the unity app would fix it. this happens in editor and play mode, regardless.

• also, it seems to randomly stop and start so it's not consistent

[rich adder]

maybe..I havent looked into it fully to know. You can probably get it to run some basic stuff

I looked into once to implement unity as a 3D viewer

[restive lantern]

Well there are PDBs available, so you could call into pretty much anything inside Unity manually, even private functions and stuff. Not sure if you'd be allowed to distribute an application that does that, but it's certainly possible.

[rich adder]

whats PDBs idk

[restive lantern]

Debug information

They contain stuff like what function is at what address etc.

[grand snow]

*for windows. Linux elf binaries do not require an external debug symbol file

[restive lantern]

It's the closest you get to Unity source code without paying extra.
And with Unity source code you could do literally anything you want anyways. But that expeeeeeensive. I think you even have to pay another extra to be allowed to distribute modified versions.

[clever gorge]

right i just started unity and its telling me that i cant enter play mode because there are compiler errors

how do i fix this because ive litterally just installed it

[slender nymph]

fix your compile errors

[cosmic dagger]

check the console to see the compile errors, ten fix to to enter play mde . . .

[polar acorn]

It is entirely possible your template contains compile errors. Possibly due to out of date packages. Check the console and update the ones that are having issues

[bright zodiac]

you sorta can without, you can do tons of things with native plugins

[restive lantern]

I have no idea about the way native things are supposed to be done tbh from a game developer perspective.

But I would assume it's well documented.

[steep whale]

can anyone find the bad logic here? Im generating rooms for a tiny dungeon crawler and the grass variances works great but the edge generation does not. what did I mess up? see screenshot for problem, it only ever generates grass grass then 5 edge then remainder grass for what should be the entire lowest x position as edges

What is safeRoomWidth set to in the inspector?

[steep whale]

i was wrong, its 5 width 5 height

[verbal dome]

Yep

So the code works

[steep whale]

beautiful, thank you for the assistance. new, stranger problem. why do you think this lower left corner is always generating without edge, even with the inspector fixed?

ignore the random grass tile off to the right, that will eventually be exit hall logic

[verbal dome]

What is safeRoomPosition.x set to

[steep whale]

x = 3 y =3

[verbal dome]

What if you set x to zero?

Or one

[steep whale]

youre the best, thank you

any advice on how to offset a second noise generation so the flower patterns dont match so closely with the grass?

[verbal dome]

I'm guessing you didn't write this code?

[steep whale]

no, im going back and forth with GPT on the designs. ive been learning compute shaders and in order to not go insane im repurposing my old 2D assets I made into something that runs

[verbal dome]

If you use chatgpt, at least try to understand the code that it feeds you

Not to sound harsh

But if you read the variable names they are pretty self explanatory

[steep whale]

i understand it at an execute level logic, so, this feeds into this, this 'should' do this, but i get lost in understanding if a function is overwriting another or if im simply implementing it poorly such as above with not catching the inspector hooks

its a learning process

[queen adder]

i'll try to explain this the best way possible, but i'm bad at explaining so sorry in advance. I have two scripts, one that instantiates a new object and one that stores a bank of values. when instantiating, the code takes one of the values from the bank script. what i need is to be able to have the instantiating script choose a random number out of say 20, then pull that specific string and use it in the instantiation. that way, it would be a random value each time it is instantiated.
here is the current code:

public void CopyTask(string newTaskData, string taskText)
{
    //do not fix or TOUCH AT ALL if this is touched everything breaks!!!
    //do not optomise in fear of project collapse
    GameObject newButton = Instantiate(buttonPrefab, buttonParent.transform);//creates new button
    newButton.gameObject.GetComponent<buttonStringKeeper>().buttonString = newTaskData;
    buttonStringKeeper data = newButton.GetComponent<buttonStringKeeper>(); //this and ^^^ could be combined but that could break so redundancy = better

    newButton.transform.GetComponentInChildren<TextMeshProUGUI>().text = taskText;//gets text component and edits it

    Button buttonComponent = newButton.GetComponent<Button>();//gets the component


    if (data != null)
    {
        // Use lambda to capture the message dynamically
        buttonComponent.onClick.AddListener(() => OpenOverlay1FromInspector(data.buttonString, newButton.gameObject)); //adds onClick with the string
    }
    else
    {
        Debug.LogError("ButtonData component not found on the button!");
    }
    //need to add listener with the button script buttonStringKeeper
    //need to pull button string keeper string and use it when opening
}

this is the instantiating script^^^

public class TaskStringBank : MonoBehaviour
{
    //STORE VARIABLES
    //call copy script with value from here
    public GameObject ModalController;
    public void callCopyScript()
    {
        string taskText = "Walk to somewhere you would have driven - 1000";
        string taskData = "Walking a short distance such as 3 miles instead of driving can help reduce emissions by between 500-1000kg of CO2 per year!|1000|google.com";
        ModalController.gameObject.GetComponent<ModalWindowController>().CopyTask(taskData, taskText);
    }


}

and this^^^ is the bank script. it is currently set up with one value. it is also the script with the function to call the instantiation. I cannot figure out the best way to do this, so any help would be great

[polar acorn]

So you just want to have a bank of taskTexts and taskDatas that you pick from randomly?

[queen adder]

yes, it needs to pick the cooresponsing two taskText's and TaskData's with each time it is called though. it probably has a simple solution but i'm not very good at this sorry

[polar acorn]

Step 1: Create a class that contains both the text and data together, so that you can keep them together.
Step 2: Change your CopyTask function to take that one object instead of two strings
Step 3: Create a list of that class that holds all available options
Step 4: Random.Range from 0 to the length of the list, then get that index from the list to grab a random selection
Step 5: Pass that value to CopyTask

[queen adder]

the reason i have them seperate is that the taskText is used to edit the TMPro child, where the taskData is used when the addlistener is called

[polar acorn]

And there's no reason you can't do that with a wrapper class

You would make a class with two string fields

and use that instead of passing the two strings directly

[frigid sequoia]

I have a script that holds a reference to all the entities in play. GameManager is gonna need a reference to it to check if the game is finished or not (check for remaining non-dead entities). I want to call this method whenever one entity dies from the entity script, and I am doubting what would be the proper way to do it, to send a reference of the list from the entity that dies as an argument (they all have a reference to list already) or to make a new reference to the list on the GameManager itself.

I don't think it would make much of a difference in this case, but I am kinda curious what would be preferred

[polar acorn]

Whenever something dies, invoke an event that other things can subscribe to. Have whatever object has the list of enemies subscribe to that event, remove that enemy from the list, and do whatever it must when the list is empty.
https://gamedevbeginner.com/events-and-delegates-in-unity/

[queen adder]

thanks this is gonna take a bit of googling to figure out how to use them but the knowing the names and such really helps

[frigid sequoia]

I am not using events at all. I checked them a bunch of times and I never find the time to use them

[polar acorn]

Well, now you have the perfect time to use them

[frigid sequoia]

Like most of times I can do with a simple standalone reference

[frigid sequoia]

Just that it would take me to refactor everything to work with events???

[sour fulcrum]

There's kind of a few ways you could put that together but like if you went way further into this than you are currently you would probably have it in the gamemanager or some comparable manager because you'd want to handle stuff like this for more than just enemies. in the past i've done something like this but it depends on a couple things

GameManager

    List<Enemy> allActiveEnemies
    UnityEvent OnEnemyRegistered
    UnityEvent OnEnemyUnregistered

    private void Awake()
        OnEnemyRegistered.AddListener(CheckLevelStatus)
        OnEnemyUnregistered.AddListener(CheckLevelStatus)

    public void RegisterEnemy(Enemy newEnemy)
        allActiveEnemies.Add(enemy)
        OnEnemyRegistered()

    public void UnregisterEnemy(Enemy enemy)
        allActiveEnemies.Remove(enemy)
        OnEnemyUnregistered()

    private void CheckLevelStatus()

Enemy

    Awake()
        GameManager.RegisterEnemy(this)

    Death()
        GameManager.UnregisterEnemy(this)

(this aligns mostly with what digiholic suggested)

[polar acorn]

Events are not an all or nothing system

[frigid sequoia]

It would be extremely weird and confusing if I use an event just for when something dies and not for anything else

[sour fulcrum]

nah

[polar acorn]

But then you'd know how to use them and could start using them more when it makes sense to

[sour fulcrum]

just do it tbh

this is using something i made so looks a little different but for example a tower defense game i made back in december had these kinda events in my gamemanager

    public static ExtendedEvent OnGameManagerEnable = new ExtendedEvent();
    public static ExtendedEvent OnGameManagerAwake = new ExtendedEvent();
    public static ExtendedEvent OnGameManagerStart = new ExtendedEvent();
    public static ExtendedEvent OnGameStart = new ExtendedEvent();
    public static ExtendedEvent<bool> OnGameEnd = new ExtendedEvent<bool>();
    public static ExtendedEvent<EnemyBehaviour> OnEnemySpawned = new ExtendedEvent<EnemyBehaviour>();
    public static ExtendedEvent OnNewWave = new ExtendedEvent<EnemyBehaviour>();
    public static ExtendedEvent OnWaveFinished = new ExtendedEvent();
    public static ExtendedEvent OnIntermissionStart = new ExtendedEvent();
    public static ExtendedEvent<EnemyBehaviour> OnEnemyKilled = new ExtendedEvent<EnemyBehaviour>();
    public static ExtendedEvent<IHighlightable> OnHighlightChanged = new ExtendedEvent<IHighlightable>();

[frigid sequoia]

I don't think it would make me good to add events now tbh....

Like it should be something I do from the start

[sour fulcrum]

at the end of the day it's your call. this is an accurate answer to the question you asked tho

[ancient stirrup]

ondestroy?

[timber tide]

You can add events whenever you want and I think an event bus is the idea here

[frigid sequoia]

I could, and I have no doubt it would be the right way to do it from the start

But everything that happens when something dies is already like well nested on all others scripts

I think it would cause more issues than anything handle that with an event now

[timber tide]

Well this would be the most proper way. Otherwise just call the singleton reference directly

[final kestrel]

When I want to initialize my singletons. It is enought to start the game at the initialization scene and I can then unload it because I'll have my dols already with me on the next scenes right?

I'm looking back at some stuff I made couple months ago but I cannot see any reason why I wanted to keep init scene loaded with the DOLs in it.

[timber tide]

What's the question? You can make a loading scene and do the manager/singleton instantiation there then load onto a main scene that will keep those managers loaded

meaning you don't need those managers in the main scene (but for development purposes I do it anyway)

[final kestrel]

Ah okay. So I understand correct. I somehow thought I needed the scripts that are dont destroy on load should stay on the initialization scene at the beginning of the game and never unload that scene to keep them active.

[timber tide]

dont destroy on load just prevents the gameobject from ever being cleaned up (from deloading) until you unflag it as is

so if you aren't using additive scenes and just load/deloading scenes then you probably want to use it for your managers

[final kestrel]

Yeah I failed to understand that it seems. Thanks for the answer!

Also another quick question. Is marking PlayerController that is responsible for your player movement/interaction etc dont destroy on load making sense? If so how can I set all the serialized references in the next scene? Because probably the next scene will have different references to hold on my player.

[cosmic dagger]

Isn't this what you were asking for, though, a solution? Events are the easiest — and honestly — the most common method. Refactoring is a part of game design, but this is not a big task to take on . . .

[timber tide]

Well, if you have stuff being serialized on each scene that's a little tricky. Initialize the manager in the scene where there are those dependent, but say the next scene have new dependencies that you want to serialize on the editor then you can just destroy the manager and recreate it on the next scene (still a singleton) but this means you lose those previous references. Otherwise you need to dynamically bind them as you enter the scene if you want to keep the persisting DDOL manager.

[frigid sequoia]

Well, I asked for between two choices and you guys told me to use a total different method that would take me like maybe a couple of hours where I could just place a single lane of code rn?

I get it, it's THE intended way

I am just not using that now

[cosmic dagger]

Understandable, but if you were going to use a single-line code rn, why not do that initially?

[final kestrel]

All right. Thanks!

[hardy ibex]

im making a rocket launcher weapon and for an explosion, would it work if i increase the hit detector colliders size, played the particles, and destroyed the bullet all at once when it hits? and if it would, is that a good way to do it?

[frigid sequoia]

I asked if it would be better to send a reference, of the list through another script that already has the reference or add a reference to the script that is gonna use the method 🤷

[sour fulcrum]

its totally valid to want to know how best to do something and decide not to do it currently 👍. I personally disagree on your take that it needs to be a all or nothing kinda implementation but you know how best to program for yourself so whatever floats your boat

[cosmic dagger]

@frigid sequoia Also, as another option, you can use an SO with a list field for your enemies and directly reference it in any script that needs the list . . .

[sour fulcrum]

@final kestrel not sure if this helps but in a lot of stuff i've made i tend to have a singleton manager that exists in DDOL (i tend to call it a GlobalManager). and a singleton that exists in the level scene/s (i tend to call this a GameManager, RoundManager etc. depending on the kinda game). Then either ither handles stuff depending on the scope of the thing they are managing

[frigid sequoia]

The script that stores the list is basically an SO, but not really

Handles just a tiny bit of other functions, but it's mostly for that

[final kestrel]

Good to know! Thanks. I'll look more into it.

[cosmic dagger]

Oh, I see. In that case, what I just suggested (using an SO with a list field) is a better option than passing the list around, and adding a script that has a reference is just stacking a dependency onto another script. That's what you want to avoid . . .

[cosmic dagger]

I mentioned using an SO because you can directly reference it from any script straight from the project folder. It avoids dependencies and you can check its status anytime . . .

[sour fulcrum]

we love so's

[cosmic dagger]

Your enemy manager script controls adding and removing the enemies while the scripts that need it will have their own field for it. It saves memory since each script will reference the same SO . . .

[sour fulcrum]

im pretty sure they were talking about instansiated enemies, no?

[frigid sequoia]

Yeah, the list of entities is a singleton basically

Is a single script on an object that hover over everything else, as well as the GameManager

[cosmic dagger]

Yeah, when instantiated, you add them to the list; when destroyed, you remove them . . .

[sour fulcrum]

I thought ideally we wanted to avoid storing runtime data on SO's

not that i don't do it just thought it wasn't the vibe suggestion wise

[frigid sequoia]

https://pastecode.io/s/3opom857

[weary basin]

hello, I'm new to unity and I'm trying to use the unity version control but it won't let me enable it for some reason... would anyone know why?

[frigid sequoia]

This is basically the list of entities that I am handling, does a bit more than just hold the data, that's why I didn't make it a SO

[cosmic dagger]

Only if you don't know what you're doing. The list is manipulated during runtime, and nothing is stored permanently. This is mainly done to save memory when multiple objects need a reference to the same data . . .

[sour fulcrum]

Heard ty chef

I forget and the unity docs are a little vague, are Awake or OnEnable suitable for resetting and/or initialization runtime data on SO's or does it need to be handled by a monobehaviour etc.

[cosmic dagger]

I tested this a while ago but can't remember all the details; it's finicky. OnDisable and OnEnable are called in the editor every time your script(s) recompile, and I believe Awake is called when the SO is created (during runtime and in the editor) . . .

[sour fulcrum]

right yeah that sounds right

i wanna maybe say if you use both to call a function that handles all the usecases?

the docs really need to be more explicit on how they work

[cosmic dagger]

You can use preprocessor directives to prevent errors in the editor for SOs . . .

[cosmic dagger]

There's a significant area of confusion for the initialization methods with SOs. I'm unsure if they updated (fixed) the docs in Unity 6 . . .

[rocky canyon]

good read

https://discussions.unity.com/t/when-is-a-scriptableobject-enabled/908460/6

Prior to this a ScriptableObject instance ONLY ever called OnEnable once per booted application session (build or editor), so it was effectively useless for initialization. Now it can be used almost as a MonoBehaviour.

Unfortunately the documentation is not clear:

[grand snow]

this caught me recently too

I rarely use scriptable objects more than just data storage so "loaded" confused me too

[acoustic belfry]

Hi just for be sure. If i have a base code with a method, and in another code wich uses that base had the sane method but with other things inside, it will override it?

[rich adder]

virtual methods can be overridden , regular method tells you if you're trying to hide the original since both run the parent one

you add new and that hides the parent one

[polar acorn]

Depends on a lot of factors. You should probably show the code that you're asking about so we can answer in specifics

[teal viper]

By "base" you're referring to inheritance or is it just a figure of speech?

[sour fulcrum]

//This class or any derivatives can be created and used.
    public class MyBaseClass
    {
        //This ALLOWS derived classes to override this function.
        public virtual void MyVirtualFunction()
        {

        }
    }

    public class MyDerivedClass : MyBaseClass
    {
        public override void MyVirtualFunction()
        {
            base.MyVirtualFunction(); //This runs the code in the virtual function. You don't have to run this if you don't want the code in the original function to run.
            //My additional code.
        }
    }

    //This class cannot be created or used, Only things deriving from it can be.
    public abstract class MyAbstractBaseClass
    {
        //This REQUIRES derived classes to override this function.
        public abstract void MyAbstractFunction();
    }

    public class MyAbstractDerivedClass : MyAbstractBaseClass
    {
        public override void MyAbstractFunction()
        {
            //There is no base implementation for this function so there's nothing to call beforehand.
            //My code that runs.
        }
    }

[rotund forum]

Hopefully someone can point me in the right direction for this;

I'm trying to create a base ENEMY CONTEXT class that I can change for each enemy type prefab I give it to (HP, ATTACK, etc.).

The issue I am encountering is I also want to be able to create an array of attacks the enemy can use... but I'm not sure how to reference the data from those attacks. I want it to be plug-and-play and tried creating an attack class array but it doesn't show on the enemy GameObject.

It seems like Scriptable Objects might be the way to go from my research, but... well I got the array to show up, but I can't add anything that derives from the scriptable object. I'm sure I'm missing something obvious here and would appreciate the help if anyone can let me know what I'm doing wrong.

[sour fulcrum]

but I can't add anything that dervice from the scriptable object.
can you provide more context on this

[polar acorn]

Are the attacks things that you define beforehand and don't change during gameplay, or are they dynamically generated or mutable in-game?

[rotund forum]

They are all defined beforehand.

[polar acorn]

Then ScriptableObjects should be what you're shooting for. You'd define the attacks in an instance of an SO. You should be able to drag those into a list of a parent type just fine

[rotund forum]

I tried creating an Attack class that enherits from ScriptableObject. I then made some class that inherited from that (e.g. Punch or Kick). Then I put a serializable Attack array in my EnemyContext class, but I can't seem to add anything to it.

[polar acorn]

You might need to use SerializeReference instead of a normal Serializefield though:
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/SerializeReference.html

[polar acorn]

What are you trying to drag into it? You need an instance of that attack, not a script file defining one

[sour fulcrum]

are you trying to add via drag n drop or by the little circle search menu

[rotund forum]

I thought part of the point of SOs was that they don't need to be instantiated? Do I still need to create a Game Object with the SO Attack?

[sour fulcrum]

you need to create a ScriptableObject

they are asset instances but not gameobjects

like a Material

[polar acorn]

You don't need a game object, but you do need an instance. Usually through the CreateAssetMenu attribute
https://docs.unity3d.com/6000.0/Documentation/ScriptReference/CreateAssetMenuAttribute.html

ScriptableObjects essentially let you define data in a file in your project, instead of in an instance that gets generated by code during runtime

[rotund forum]

Hmm. Probably where I am seeing trouble. I have a version of Unity where there is no option to just create a ScriptableObject. I thought it was enough to add the inheritance to the class.

[sour fulcrum]

click the link above

theres an example of it being used here https://docs.unity3d.com/Manual/class-ScriptableObject.html

[polar acorn]

No version of unity lets you just create a scriptable object. You have to do that

[teal viper]

There is no unity version that allows you creating a ScriptableObject instance in the menu.

[polar acorn]

Chance are, you don't even need the child classes. If you define your Attack SO well enough, you just need multiple instances of it

[trim solar]

my friend needs help with a unreal engine 5.5 problem, is there a unreal engine equivlent to this discord ?

[sour fulcrum]

Really depends on the context no?

[polar acorn]

Like, one of them would have the name Punch and the damage value of 10 and speed 3 while Kick would have 20 damage and speed 1 or something

[rotund forum]

So this isn't that then?

https://youtu.be/PVOVIxNxxeQ?t=96

[sour fulcrum]

why is that part just cut off like that wtf

[polar acorn]

Scroll back

It's that thing I said you had to do

Unity doesn't just do that. You have to tell it to do that

[polar acorn]

Probably. Do whatever you did to find this one to find that one instead

[rotund forum]

Ahh. I see now.

My brain is expanding.

Thank you.

@sour fulcrum @polar acorn Thanks again guys; I started making INSTANCES of the SOs and now everything has come full circle. This is exactly what I needed.

🙂

[acoustic belfry]

in theory

[teal viper]

The virtual/override rules apply.

[acoustic belfry]

ok, holup

using UnityEditor.Purchasing;
using UnityEngine;


public class mortem_rifle_script : EnemyBase
{
 void chase()
 {
     Debug.Log("deberia estar persiguiendote");
     chasing = true;
     if (debeDisparar == true && reload == false)
     {
         if (distanciaAbsoluta > rangoDisparo)
         {

             animator.Play("Base Layer.MRifle_Walk");
             transform.position = Vector2.MoveTowards(transform.position, objetivo.position, runSpeed * Time.deltaTime);
             bullettimer -= Time.deltaTime;
             if (bullettimer <= 0)
             {
                 bullettimer = firingspeed;
                 disparar();
             }
         }
         else
         {
             bullettimer -= Time.deltaTime;
             if (bullettimer <= 0)
             {
                 bullettimer = firingspeed;
                 disparar();
             }
         }

     }

 }
}```

public class EnemyBase : MonoBehaviour
{
    public int health;
    public Vector2 boxSize;
    public float distanceRay;
    public LayerMask groundlayer;

     void update{
chase()
]

  void chase()
{
debug.log("u need an chasing code in ur enemy")
}

}```

[sour fulcrum]

just a heads up that function and class names should be UpperCase and class names shouldn't contain underscores. Ideally that would be MortemRifle : EnemyBase

[polar acorn]

Looks like you have a function in your function

[acoustic belfry]

woops, i just edited this cuz i haven't implemented this yet in my code, i just wanted to make an example, let me fix it

[teal viper]

Without virtual/override, the method called would depend on the reference type.

[acoustic belfry]

so i just put the sufix virtual on all the methods in my base, and then put override in the methods of my enemy?

[teal viper]

So if it's a mortem_rifle_script reference, the chase method defined in it would be called. If it's the base class reference(even if the instance is actually the extending class), then the base class method would be called.

[teal viper]

Only on the methods that you want to override.

[acoustic belfry]

got it, thanks :3

[stuck palm]

if I have an editor script added to a gameobject, will it strip it from the gameobject in the build?

[teal viper]

Editor script attached as a component?? What makes it an editor script?

[twin pivot]

https://paste.mod.gg/bwyhoinprflu/0

im getting a null reference at line 20 and 24

the script component i attached to it gets deleted when i start the game for some reason

[slender nymph]

then you haven't assigned the variable upgrade1
https://unity.huh.how/runtime-exceptions/nullreferenceexception

or rather more specifically, the object with this component on it does not also have an Upgrade1 component on it

[twin pivot]

i did add the component but it just deletes itself when i start the game

[slender nymph]

then show its code

[twin pivot]

i commented it out in here

[slender nymph]

that is a single method that isn't even what would cause it to delete itself

[frigid sequoia]

What's.... the difference between these 2?

[twin pivot]

im instantiating all of these objects, would that be a problem?

[slender nymph]

the second is deprecated

literally how the fuck should i know if you won't show relevant code for that

[slender nymph]

okay now show the code i actually asked for

[twin pivot]

the code in upgrade1?

[slender nymph]

yes

[twin pivot]

https://paste.mod.gg/zksrrriyvaib/0

[slender nymph]

well there's nothing there that would cause it to be destroyed, so you're gonna need to investigate what could possibly be destroying that component

[twin pivot]

yes i am aware

i was asking if instantiating a copy of all of these could be what was causing this

[frigid sequoia]

But it pretty much still works...

Okay, I will use the other one then

[slender nymph]

obviously instantiating an object does not destroy it.

[slender nymph]

that's because you are on a version of unity where it is deprecated but not yet obsolete. if you were using unity 6 then it would be obsolete and you would have a compile error for it

[frigid sequoia]

Any particular reason why that method is no longer in use? Seems pretty alright

[twin pivot]

it could be directing to a different copy of upgrade1 than intended

[frigid sequoia]

I guess they touched the whole gameObject scripts

[slender nymph]

that doesn't make any sense

[slender nymph]

the FindObjectXXX methods were deprecated in favor of a group of methods that can optionally perform the sorting that the previous versions of the methods were already doing. FindFirstObjectByType does exactly what FindObjectOfType did, it gets all of the objects of that type, sorts them by instance ID then returns the first. There is an alternative FindAnyObjectByType that does not do that sorting though

[strong wren]

The deprecation message should show you this information. Make sure your IDE is configured.

[frigid sequoia]

There is just a single one, so i guess I should do the FindAny

[slender nymph]

or use a better way to get a reference, even the unity docs suggest using the singleton pattern over the Find methods if you only have a single object of that type

[frigid sequoia]

I don't think it does, no

[slender nymph]

afaik there isn't one in 2022, only in 6

[strong wren]

Ah, makes sense for a backport.

[sour fulcrum]

wasn't it introduced earlier than 6 tho

[slender nymph]

in 2022.2, which is also when 2023 was in alpha. so new addition for 2023, but backported to 2022.2

[frigid sequoia]

Oh, yeah, I should totally be using that as singleton, I don't know why I wasn't

In fact all these should, huh

Is there a way to make the whole Main Components and its children don't destroy on load from the inspector or do I have to make a script just for that?

[slender nymph]

gotta do that in code

[cosmic dagger]

A simple way is to slap a DDOL script on the parent . . .

[twin pivot]

idk man im just throwing random suggestions and seeing what sticks

[frigid sequoia]

Yep, that's what I am doing

I have a question, it's not gonna happen, but I am like curious to know how this goes. How does it work when you have stored data and release a new build? In like.... Let's say you just realized a particular weapon is way too strong and decide to tune it down but the player already has that as saved data on their character? I am guessing you would need to save all that kinda stuff as SO and the player just saves references to those that get updated as soon as used?

Else the player would find that... his wooden sword in particular is like damage 10 but all others wooden swords for now on are like 8?

[teal viper]

It depends what and how you save. In most cases, it would just be IDs of items. So when they load a game after updating it would be using the new item stats(assuming the I'd didn't change).

Some games might have stat randomization or modification features. Depending on how they are implemented, the player might indeed retain stats from before the update.

Basically, it's all up to you

[sour fulcrum]

scriptableobject changes at runtime are not saved incase that was an assumption your having

[frigid sequoia]

The thing is... the player is intended to ultimately assembly a whole roster of players of different clases, with different stats, skills and equipment. I would need to store the whole roster as saved data, and be able to modify it later if needed

So for example if the player saves a warlock on the roster and that warlock has a summon imp skill; if I want to later modify the skill and affect all players it would need to be stored as an static SO and just give the player the reference to that right?

[sour fulcrum]

when you mean save do you mean in a single play session or multiple play sessions

[teal viper]

You'd save an ID. You never need to save actual data(unless there's a specific reason to do that)

[frigid sequoia]

This does not even save at all yet, but if I want to do it, I have to set it up now. But I do mean over multiple play sessions

[sour fulcrum]

then yeah

if you launch a game, modify a scriptableobject and close the game the scriptableobject won't save that change

you need to compose a way to save stuff yourself (usually using Json)

[frigid sequoia]

Ok... and can I just add whole scripts to a SO no issue right?

[sour fulcrum]

i have no clue what that means with and without the context of this conversation

[frigid sequoia]

I mean, in the previous example. I would need to have a reference to what a warlock is through a SO (cause I intend to save the player having one of those). This implies several scripts attached, one for each skill for example. If I want to modify the whole logic of an skill I would have SO that has a reference to that script of the skill.

[sour fulcrum]

the word script does not make sense in this sentance

do you mean another scriptableobject? a monobehaviour? a base class?

because you don't put scripts anywhere

[teal viper]

Also:

1. You should avoid modifying SOs at runtime.
2. I'm not sure what meaning you put into "save the player having one of those"). You don't save the whole player GameObject with references. That's not how it works

[frigid sequoia]

I do not intend to modify SO at runtime whatsoever

And I would need to save a player having X character on the roster. These all are the scripts that make a character for now. All these are mostly common to all entities. But a rogue in particular has X stats, a particular behavior script for him alone a skill script that is particular to them

I could save the rogue as a prefab and make the save date "Player has a rogue", but I would need to save like different instances of that rogue not being any rogue, but THAT particular rogue. It having stuff like equipment or a given name. That could not be saved as part of a prefab. So I would need to store all that as SO?

[teal viper]

You'd need to create serializable data for each of the scripts and save it as json or something.

[sour fulcrum]

You cannot save gameobjects or scriptableobjects at runtime

[frigid sequoia]

I mean in the editor, not a runtime

[sour fulcrum]

based on the messages in this conversation i don't know if that is true?

[teal viper]

In the editor you can save it however you want, whether it's a prefab, SO or just data saved in json.

[frigid sequoia]

I mean, it would be fucking great if could just plug the whole gameobject and save it, but I know that's not a thing sadly

[teal viper]

Yeah, I also had the feeling we're talking about save game system

[obtuse ether]

coding in something to send you to the next level while also saving what level you're on

[sour fulcrum]

thats why i asked this and that your original question was about how save data works in a new build

[obtuse ether]

and for some reason its skipping from level 2 to level 4

and its triggering ontriggerenter twice i think?

anyone know why

[eternal needle]

you have debugs, is it triggering twice or not? if it is, print more logs about like what you collided with

[teal viper]

Make your logs more verbose. Log the values that are being used/passed around.

[obtuse ether]

alright

[obtuse ether]

checked and now i understand whats happening lol

shouldve checked tag of the thing colliding w it

bc if anything enters its trigger then poof next level

[obtuse ether]

yea thanks a lot for the advice lol

[twin pivot]

https://paste.mod.gg/bwyhoinprflu/0 upgrade 1 keeps getting unassigned (i think its because both the original and instantiated copy is running the lines in void start)

[teal viper]

Unassigned when? Where?

How do you know that?
Is it assigned in the first place?

[ruby zephyr]

May I already try making extremely simple games to practice? As I am only able to learn programming in c# and Don't have any idea how to program on Unity since I never had the idea of trying.

Here's a summary of what I know in c#

Basics of C#: Variables, data types, input/output, type conversion

Conditional Statements: if, else if, else, nested conditionals

Operators: Relational (>, <, ==, !=), Logical (&&, ||)

Basic User Input Handling: Reading and validating input (Convert.ToInt32, ReadLine)

Basic Debugging Skills: Identifying syntax errors and logical mistakes

Simple Programs: Grade average calculator, username-password validation```

I wanna apply these to Unity to at least experience programming in Unity while Learning c#

[ivory bobcat]

You would not be able to apply i/o operations from console applications

[eternal needle]

is this like some AI section of text you've written? Its worded quite AI like

May I already try making extremely simple games to practice
Yea no ones stopping you. Id say it might be better if you understand classes/instances first but its not impossible to learn in unity too

Yea maybe dont do that. And also don't use AI generated anything here

no one wants to read AI written text and definitely dont want to be responded with it either

and they dont even know theyre actually lying

[eternal needle]

is that really such a shocker? if you cant put in basic effort to say you learned if statements then what kind of effort should people put to help you? Imagine if someone went straight to chatgpt to respond to your question

lets say u learnt to chapter 6 , and u ask chatgpt, it may confidently answer

yes, now you have learnt to chapter 3 so far

if its solely translating language, welp ppl will know, i mean we know english right?

but normally google translator should do....

[eternal needle]

moving on from the whole AI part, truthfully you've learned the absolute basics of c#. I suggest looking more into functions, classes/instances, and then you'd have an ok foundation to at least understand how things work in unity.

[ruby zephyr]

Alrightt, should I learn some in Unity since classes are in Unity right? I dont even know what to call them

[eternal needle]

you can say you learned if statements and variables, but at the same time you've had so little experience it's doubtful you'd be able to write these programs easily

Oh, how about rigid body things

[nimble apex]

C# is similar to java, its an evolution to that

in java, everything must wrapped into container, except using statements , same for C# i guess

[eternal needle]

Unity has components, which are classes yes, but you're going to be very confused if you don't understand how to access information on a class

[nimble apex]

the main container is class

[ivory bobcat]

Components, which you can learn along with the tutorial link above #💻┃code-beginner message

[nimble apex]

public class abcde{
     //content
}```

[eternal needle]

🤔 did they say anything about knowing java, this would honestly just be more confusing to me if i was learning anyways

[ruby zephyr]

Because they say we can freely join game jams, and I kinda wanna join one for experience, but since I don't even know how to apply my knowledge in Unity, how would I do.

[eternal needle]

the best thing is really not to try and teach such concepts and let them go use actual guides imo.

[nimble apex]

go visit learn.unity.com

u should have the link already

[shrewd gazelle]

hey guys if a script has name space in it do you guys know how I. an access variables from another script becuase it is not letting me

[ruby zephyr]

Is this the right place?

[polar acorn]

Add a using statement for the namespace it's in to the top of the script you're trying to use it in

[shrewd gazelle]

using System.Collections.Generic; you mean this ?

[polar acorn]

Assuming the code you want to use is in the namespace System.Collections.Generic, yes

[shrewd gazelle]

So I want to use variable from another script inside the script that has namespace in it. but if theres no way to do that I think I can figure it out based on what you said.

[polar acorn]

Once you add the using statement the namespace no longer has any effect

[teal viper]

As script being inside a namespace, doesn't affect what it can access in any way.

At least not in regards to code outside the namespace.

[teal viper]

You should share your code with the issue if you need proper help.

[shrewd gazelle]

ok Ill share it but fyi Im aware that my script is not clean Ill clean it later lol. what was that website that you guys use to share

I put both scripts on top of each other

[teal viper]

sonartakestuff = FindObjectOfType<Sonartake>();// this is not working
What do you mean by "this is not working"? Does it assign null?

[shrewd gazelle]

this is what I get in my console

[frigid sequoia]

Ok, I am extremely confused, cause I turned all those scripts into singletons and make them don't destroy on load and now it's returning me this error. But... it doesn't make sense, cause it's working, and that could not work without a reference at all so....

Wtf?

[teal viper]

Are they in the same assembly?

[teal viper]

Open both scripts in visual studio and take a screenshot of the whole window.

[teal viper]

Perhaps you're accessing the singleton before it's instance is assigned.

[frigid sequoia]

Yeah, that's the only thing that could be happening, but... the script is working, at the same time that is telling me it does not have a reference to the players... how?

I am extremely confused

[shrewd gazelle]

like this @teal viper

[teal viper]

Who knows perhaps you have several of these scripts and some of them initialize properly. You should debug it.

[teal viper]

Mmm... Vs code is not gonna help much. Especially since it not configured correctly for unity.

[keen owl]

try applying a null check for the instance and assign it this

[shrewd gazelle]

this is visual studio code the blue one

[teal viper]

Does it work if you put both scripts in the same path?

[frigid sequoia]

Oh, I think it's calling the OnEnable twice

[teal viper]

Yes, that's what I said. I was talking about Visual studio(not code, the purple one).

[frigid sequoia]

Does that trigger by default at the start if the component starts enabled?

[teal viper]

Yes, it should be

[shrewd gazelle]

havent tried that and I dont think the project manager is gonna want me to do that lol

[teal viper]

Well, there's not much I can help you with then. Unless you can tell me if both scripts are in the same assembly.

[shrewd gazelle]

when you say same assembly you mean the same script or am i misunderstanding

[teal viper]

No. In C#, code can belong to different assemblies. These would normally compile to separate dlls. Basically, separate modules of a program. Code in one assembly can't see code in another, unless the other assembly is referenced correctly.

If you have a project manager, maybe ask them for help. They should know enough about the project to tell you why the other script is not recognized in your code.

[shrewd gazelle]

belive me if i had that option I wouldve done that but he is very busy and all the coders are becuase we got deadlines and exams coming up and I only need to access a boolean and clean my code and Im done. but its fine ill try to find a way to fix this and hopefully I will

[teal viper]

You can also install visual studio and take screenshots that I asked for.

[shrewd gazelle]

I thought it doesn't work on mac anymore but I might try that

[twin pivot]

When i start the game, a script thats a component of tmp text, before i start it it says it was assigned but if i check after i start it its no longer there

oh my god i just figured it out

Hello, unity noob over here, I experimented a bit with RPC calls and was wondering if fusion + photon voice would be a good solution for a solo project by a beginner ( I have C# xp, just 0 experience game developing )

The project I'm making is based on proximity chat

[hot harbor]

What's a good way to expose the tag property of a gameObject, similar to how one would do layermasks for rigidbodies?

As in I could expose it as a public field and modify the values

I searched and came across editorGui.Tagfield but that's not exactly what I needed

For context I wanted to have a way to distinguish between ally and enemy projectiles, and they happen to be on the same layer so tags were the choice that came to mind

However I wanted to use a scriptableObject for the configuration and seting the tag instead of manually configuring each prefab

[fleet onyx]

hello, does anyone knows what this error is? :

TransientArtifactProvider::IsTransientArtifact call is not allowed when transient artifacts are getting updated

[burnt vapor]

Sounds like an internal Unity error. If it keeps happening restart the editor and see if it is fixed

[gleaming bridge]

silly question but how do i round of the edges for a square image

[frosty hound]

Not a code question. #📲┃ui-ux

You cannot, you need to create an actual sprite. Alternatively, you can buy one of the procedural UI assets off the store.

[obtuse sluice]

        animator.SetBool("Walk", horizontalMovement != 0);
        animator.SetBool("Jump", !isGrounded && rb.linearVelocity.y > 0);
        animator.SetBool("Fall", !isGrounded && rb.linearVelocity.y < 0 && !isWallJumping);

Can someone help me where my logic is maybe wrong?
so every animation works well, just the fall wont trigger

I set
Jump => Fall to true
and
Fall => Idle to false

[burnt vapor]

https://unity.huh.how/debugging
Debug your values and verify the boolean is actually being set as you expect.

[obtuse sluice]

Okay got it nearly right now. now the jump is sometimes triggered after fall instead of idle. I try to fix it

[stray wigeon]

Hey, I'm new to unity, trying to make a small game prototype with some funky movement. I am kind of confused as to why I do not have code autofill (tab) or hints about what certain functions or lines of code do for VScode like most guides show? I have Unity Code Snippets installed and the Unity extension for vscode. Any ideas?

[frosty hound]

You can try following the !ide instructions here:

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• :question: Other/None

[frosty hound]

VSCode is finniky at best though. If you want something reliable, use Visual Studio or Rider.

[stray wigeon]

Dang, I did everything in that vscode guide and it goes from this:

to this in a couple seconds:

And intellisense still doesn't work. Guess it's time to just switch to VS

[frosty hound]

Yeah, I don't use VSCode at all for Unity

[slender nymph]

switching to vs is probably the better solution, but you can also check out this list of troubleshooting steps for vs code: https://unity.huh.how/ide-configuration/visual-studio-code#if-you-are-experiencing-issues

[stray wigeon]

Thank you, would have spent 100000 years trying to fix vscode. Everything works with an updated VS.

[stray wigeon]

Thanks for the tip, I might try it at home with my other PC same issue there.

[polar dust]

VSC isnt a "real" IDE, its basically a text editor with extensions to let you do IDE things

[verbal dome]

In practice it does pretty much everything that VS does

In unity context at least

[hot harbor]

I was wondering if anyone could give me some suggestions on configuring 2d movement?

I've implemented the entire thing based on modular movements where every move is a scriptableObject to be executed by a state machine that has an array of said movements

My question is if there was an easier way/better way(s) of setting this up, since I've found that every small change in say, speed or direction values calls for a new scriptableObject

Code is in pastebin
https://pastebin.com/HJCcbc88

Also i'm aware that if I want collisions it'd be best to use rigidbody.Move; I've just yet to refactor things

[verbal dome]

Do you really need the moves to be this configurable/modular, instead of just making concrete classes/functions for different moves? Do the moves always share a lot of common variables?

[verbal dome]

calls for a new scriptableObject
Wdym by this?

[hot harbor]

For some context I'm trying to make a shmup, and I figured the best way to have control over the movement was to decompose it into this form

[verbal dome]

If you are referencing a scriptableobject, you aren't creating a new one (hopefully) every time you read its variables

[hot harbor]

My bad I meant if I had say, a move that's linearly to the right, but now I want the same move except change in direction; currently I have things set up where these two need to be two separate scriptableObjects

[hot harbor]

No no that's not what I was doing

[verbal dome]

Yeah the direction being tied to each scriptable object instance feels weird to me

[hot harbor]

I set it up this way so that I could change directions whenever I wanted, move right first, then move circularly, then move left etc etc

what did you have in mind instead of this?

I also think it's quite cumbersome...

[verbal dome]

Idk, the caller passing in the direction as a parameter

But i don't know enough about your game to judge it

One idea is to make the MoveConfig abstract and split it into child classes that implement only the stuff they need

[hot harbor]

I haven't thought about doing it that way!

I even wrote a custom editor just to separate linear from circular and etc etc😂 proves to be completely unnecessary if I had split them into child classes

Thanks

[slow knot]

does making a completely physics based camera as a gimmic work well, not just like its affected by physics but like almost like it moves back and fourth based on how fast you go and stop almost like a cartoon at sudden movements

[verbal dome]

I would so that with some math, tweens and/or animations, not with actual rigidbodies or anything like that

[slow knot]

is this the wrong channel for that question?

[slow knot]

im calling daddy gpt for the math 🙏 i am not smart enough to calculate that shi

[verbal dome]

Or do you need collisions and physucal interactions with the camera?

[slow knot]

maybe its not fully decided but one of my ideas was to have the camera move with the head which uh i now realize i should probably just write a normal camera script and acnhor it to the head and make the ehad do the calculations...

[slow knot]

but yeah probably

maybe the head anchoring method would work better, either way im almost done with the rigidbody camera script and ill have to test it out... afterrr i fix my bad ahh player movement

[stray wigeon]

Not sure where to ask, but I can't get grid snapping to work with rotation. Only XYZ movement. Or does unity not support that?

[verbal dome]

Hold ctrl (or shift?) While rotating to snap

#💻┃unity-talk next time

[stray wigeon]

Ctrl works. Thanks. Couldn't find it for the life of me. (Or I am just bad at google)

[stray wigeon]

Thanks, sorry.

[vague charm]

Hello, I am trying to make the water tiles in my game add speed to the user when they interact with the water but every time I try to add a tile with a script to the tile palette it won't appear to place. I thought I was supposed to make a prefab and then I would be able to make them but I'm not quite sure what I am doing wrong

[rich adder]

this is not how you make tile

Tiles arent meant to be GameObject / SpriteRenderer

drag the sprite tile from the project folder and put them in the Tile Palette

On that note if you want to use GameObject as tile (for interactions and whatnot) Then you use gameobject brush instead. These can't be put in tile palette but also they are nested in tilemap object but they are not part of the tilemap technically

[vague charm]

I see, I was trying to add them straight to the palette(after the script was attached) but it kept saying invalid. So am I sup--ooooooh

Ok i will give that a try

It worked 😭 thank you very much

[polar acorn]

Rigidbody.velocity is now Rigidbody.linearVelocity in Unity 6

There is no such thing as .velocity any more, anywhere

[rich adder]

huh why does a camera have velocity anyway?

[polar acorn]

It was renamed to avoid ambiguity with angularVelocity, which has always existed

But technically the field velocity would imply it controlled both

Which it never has

[pure drift]

https://paste.myst.rs/gtnn6dq2 with this code how can i make my asteroids spawn smaller versions of themselves 2 times right now it splits apart once but i cant do it after that

[polar acorn]

You should have a script on the asteroid that detects when it's shot, spawns in the smaller versions of itself, then destroys itself.
You make the smallest asteroid do everything but the "spawning more" thing

So, a script with a field for "SmallerAsteroidPrefab" or something, and as long as that's not null, spawn two of that when it dies

[pure drift]

https://paste.myst.rs/ibbsce08 could i use this script

[polar acorn]

You could use whatever script you want

[rare elm]

hi. i bought a game kit that uses a Timeline to define when creatures should be added

mostly it's a good metaphor, but there are times at which having it as code or data would be better (mostly during bulk editing)

is the timeline a UI only thing, or is there some way to get it as code/data?

[polar acorn]

But the easiest way is one on the asteroid itself

[maiden totem]

just to make sure, Player.Look is already affected by framerate and will be smaller the higher the framerate is? So I don't need to multiply the lookVector.x * mouseSensitivity by Time.deltaTime? Or do I still need to? Assuming this is in Update()

[slender nymph]

if it is mouse input then yes, it is already framerate independent. if it is joystick input then no, it is not

[maiden totem]

So I don't need to multiply by deltaTime I suppose?

[slender nymph]

you do when it is being used for joystick input

[maiden totem]

Hmm, I see. Thank you very much! :D

[pure drift]

intresting thank you

For anyone that took Unity programming pathway, how sufficient did you find the course?

gimmic, mostly testing it out but i thought that maybe it made for a unique concept if done right, im still coding it but still fixing logic etc becasue i suck lmao

right now its just seizure simulator since its like 80 lines which isnt enough for this really. and at the same time im bad at these kinds of maths so i might be cooked

also how do i call this function

[rich adder]

Unity calls this function when there is a collision exited between a rigidbody +collider and another rigidbody/collider

[slow knot]

ah so i dont need to add it to my update loop? great

[rich adder]

na. Just like Update these are called by unity

[pure drift]

i dont know if youre still here but how would i have it in different stages for the asteroids like the bigger one breaks into two medium ones and if you break one of the medium ones you get two smaller ones

[polar acorn]

By changing which prefab that script references

[pure drift]

ohh ok thank you so youre saying i shouldnt do it like how i am doing it right now i should create two prefab varients

[edgy spruce]

Does this always take so long to download?

[pure drift]

or do i have only one for the smallest one

[mystic ferry]

Yep.

do you know how long aproximatly?

[mystic ferry]

I don’t know but I remember it taking too long last time I did it and I just went to sleep and let it do its thing. So I’m not sure. An hour or more?

[silent valley]

I'd assume the download would differ depending on your internet speed. Some may take 30 mins, some may take a whole day

[rare basin]

anyone might be able to help me? i am trying to make drag&drop inventory system, but cannout figure out, why the OnBeginDrag doesn't work.

public void OnBeginDrag(PointerEventData eventData)
{
    print("begin drag");
    if(CurrentItem == null) return;

    _dragHandler.StartDrag(this);
}

I have implemented the IBeginDragHandler interface

and I do have a Image component

on that MonoBehaviour

and nothing overlapping that image

and event system present

[slender nymph]

view the event system at runtime to see what it detects when you try to drag that object

[rare basin]

the Selected: at the very bottom?

[slender nymph]

it has a preview window at the bottom of its inspector that will show you useful info like that

[rare basin]

yea it's always nothing

even when i hover the mouse over my inventory slots

just wondering what's wrong, as I have nothing above the inventory slots, just started the project

that's the only UI I have

[slender nymph]

and if you actually set a sprite on the image does it work?

[rare basin]

no, doesnt work aswell

but if i add a Button component under the inventory slot

it's interactable

changes color on hover etc

i thought it's possible to make IBeginDragHandler with just a Image, right?

[slender nymph]

it is. which component actually implements the interface?

[rare basin]

InventorySlot

[slender nymph]

and your canvas has a GraphicRaycaster, yes?

[rare basin]

yes

here is inventory slot if it helps with anything: https://pastebin.com/en0tjHTG

the InventorySlot object doesn't have Image comopnent, the background and item icon has

but I have also tried adding one

same result

[slender nymph]

the object that actually has the component that implements the relevant event system interface has to be the one with a graphic that can be raycasted against. so if InventorySlot has the InventorySlot component then it must be the object with the image on it and there cannot be another image overlapping it (like Background and/or Item Icon) unless those are not raycast targets

[rare basin]

okay got it, but it still doesnt work as i mentioned

this is inventory slot, with image as a raycast target

background and item icon has raycast target DISABLED on their images

it still doesnt print for whatever reason

there is absolutely nothing else covering/overlapping the inventory slot image

funny thing is, that when i add EventTrigger comopnent

to InventorySlot

and assign something random to just test if its working

then its working

yes my VS is saved 😄

[slender nymph]

are you sure about that

[rare basin]

yes

[slender nymph]

did you make sure it actually compiled too?

[rare basin]

yes

i have even restarted unity and PC

there is even a thing like that in inspector

why would EventTrigger work but not IBeginDragHandler

on same setup

[rare basin]

and what is even more interesting, triggering this via EventTrigger, also prints my message in code

[slender nymph]

if you also implement IDragHandler does it start working?

[rare basin]

umm yea lol

it works now

[slender nymph]

okay so i guess IBegin/EndDragHandler require IDragHandler to work. which kind of makes sense considering you can't begin dragging without also dragging

plus you probably wanted full drag functionality and not just detecting when dragging has only started

[rare basin]

so my idea was that i will handle

all dragging and dropping in

InventoryDragHandler instead

should I keep everything inside InventorySlot then? I wanted to kinda separate it to keep single-resposnbility

[slender nymph]

how would that separate object detect when you have stopped dragging

[rare basin]

i did OnEndDrag in InventoryDragHandler

and OnDrag

[slender nymph]

okay, so how would that detect when you've stopped dragging a completely different object

[rare basin]

so basically i did only start drag in InventorySlot then activated drag handler and the ondrag started to work there

[slender nymph]

again, neither OnDrag nor OnEndDrag would be called on a separate object

[rare basin]

hm, i see 😄

then i will do it all in InventorySlot

thanks

[slender nymph]

you can still separate that functionality out to a different component, but that component just has to be attached to the object being dragged

[rare basin]

i just had a issue, where when I was dragging a Image's rect transform

from a slot1

it was "under" slots10

so i wanted to set it as last sibling temporarily

when dragging it, and setting it back as a child to original slot

is that a good idea?

it works, tyvm

oh and btw @slender nymph, you don't even need Image on the InventorySlot component, just having the Image as a child works aswell

just wanted to lyk

https://paste.myst.rs/u7x4z234

Nothing in this code seems to be moving them in the first place

Well, it wraps if it's off screen

So what actually moves the objects

[pure drift]

oh i have this code: https://paste.myst.rs/rfb9zbgm

[polar acorn]

Looks like they pull their speed from data.maxDirections in Start. You could just multiply that result by something to scale it up or down

Yeah that's probably the best way

[proud bloom]

hi, im having an issue where my bullet prefab that holds the bullet script wont let me assign the enemy gameobject or the empty EnemySpawn onto it. i try and it says type mismatch. here is how i have it set up, any help would be appreciated. this is the code, im trying to enable the Enemy after disabling it when its hit by a bullet.
https://paste.myst.rs/6dazt4rj

[polar acorn]

Prefabs cannot reference objects in scenes.

you need to set the reference on the instance of the bullet after you spawn it

[proud bloom]

Hmm ok thats what i figured, how would i go about doing that? this is where i instantiate my bullet in my player script. i have a empty gameobj for the bullets to go into on spawn would i do anything with that?

[polar acorn]

What type is BulletPrefab

[proud bloom]

GameObject

[polar acorn]

You should use the type you actually want instead, most likely Bullet.

Then, instantiate will return a reference to that Bullet and you can set its Enemy field

[proud bloom]

this is all im using besides my bullet script and my prefab

[grand snow]

as suggested, do:

[SerializeField]
Bullet bulletPrefab;
...
Bullet newBullet = Instantiate(bulletPrefab);
newBullet.Enemy = foobar;

[proud bloom]

thank you ill try that

[onyx narwhal]

does anyone know how to rotate a capsule collider in Unity 2D? 😭

[timber tide]

Usually you can flip stuff by setting the x scale negative but not sure how that works with physics

otherwise flip the collider values in a script

[onyx narwhal]

damm i thought there was just a "rotate collider" button or something 😭

[teal viper]

Collider always aligns with the object axis. So if there's anything you need to rotate, it's the sprite. Or you could add the collider as a child and rotate that child object.

I'm general, you should keep visuals separate(separate gameObjects) from physics and game logic

[neon forum]

why, when naming my script "game Manager" it became a funny gear?

[wintry quarry]

Just a special icon for that special name. It doesn't do anything else

[neon forum]

ah, okay, ty

[wintry quarry]

Kind of a Unity Easter egg tbh

[neon forum]

neat

did old unity scripts always look like gears?

[wintry quarry]

No just GameManager

[neon forum]

fair enough

[sand mesa]

my public variables aren't showing up in the inspector

any ideas?

[timber tide]

Ya got a canvas on the GO

rect transform even

Ah, you're just serializing other images onto this manager

[wintry quarry]

Are those the right kind of Image?

[timber tide]

Yeah wrong namespace probably

[wintry quarry]

Make sure you have using UnityEngine.UI instead of using UnityEngine.UIElements;

[sand mesa]

oh

[timber tide]

Don't need that SerializeField either if you set it as public

[wintry quarry]

i'm sure that was an attempt to debug/fix but yes

[sand mesa]

chears

[sand mesa]

... hm

why is it saying opened dialogue has content, but closed doesnt?

[sour fulcrum]

the field declarations there only apply when the class is initialized

[wintry quarry]

because you serialized it without any content

reset your component

[sour fulcrum]

so if you added that component before adding that "locked. damnit" it won't appear after the fact

[sand mesa]

oh i see

[polar acorn]

The values you put in code for a serialized field are just the default values

The inspector takes precedence

[noble forum]

Hey, i feel dumb asking this as i have been programming in unity for a while, but im left confused. It seems i get the null from that but at the same time it is assigned?

[glacial forge]

what is the correct way to get a tilemap collision? I see there are multiple collider functions you can use OnCollisionEnter2D and OnTriggerEnter are 2 that i have tried, but none are working

here is my current code

private void OnCollisionEnter2D(Collision2D other)
{
 Debug.Log(other.gameObject.tag.ToString());
}

This is attached to my player which has a rigid body 2d and a circle collider. My tile map has a tilemap collider and its tag is set to "World", yet when i play the game nothing happens. i turned trigger on (for both player and tilemap) when using the on triggerenter method

[wintry quarry]

the code is running twice

once it works properly

the other time it throws an error

You might have multiple copies of the script in the scene

[noble forum]

Oh, that would explain things

Only that im almost sure its a single copy, let me see

Is the player's Rigidbody dynamic or kinematic?

[glacial forge]

dynamic

not sure what the difference is there

so i left it default

[rich adder]

how you move the player, show code

[glacial forge]

void ApplyMovement()
{
    float speed = moveSpeed;
    if (inputHandler.SprintValue > 0)
    {
        animator.speed = sprintMultiplier;
        speed *= sprintMultiplier;
    }
    rb.linearVelocity = new Vector2 (velocity.x * speed, velocity.y * speed);
    //animator.SetFloat("Horizontal", velocity.x);
    //animator.SetFloat("Vertical", velocity.y);
    //animator.SetFloat("Speed", velocity.sqrMagnitude);
    
}

that function is called in fixedupdate

[noble forum]

It's quite a big script, so there is no way i missed another copy

Also i don't see it anywhere

[glacial forge]

velocity comes from my input handler

private void Awake()
{
    if (Instance == null)
    {
        Instance = this;
        DontDestroyOnLoad(gameObject);
    }
    else
    {
        Destroy(gameObject);
    }

    moveAction = playerControls.FindActionMap(actionMapName).FindAction(move);
    jumpAction = playerControls.FindActionMap(actionMapName).FindAction(jump);
    sprintAction = playerControls.FindActionMap(actionMapName).FindAction(sprint);
    RegisterInputActions();
}

void RegisterInputActions()
{
    moveAction.performed += context => MoveInput = context.ReadValue<Vector2>();
    moveAction.canceled += context => MoveInput = Vector2.zero;

    jumpAction.performed += context => JumpTriggered = true;
    jumpAction.canceled += context => JumpTriggered = false;

    sprintAction.performed += context => SprintValue = context.ReadValue<float>();
    sprintAction.canceled += context => SprintValue = 0f;

}

This is just getting the inputs from the input system and assigning a vector based on that for the player controller to access

[rich adder]

looks fine there. Maybe ss both tilemap and player inspectors

[glacial forge]

Player:

Tilemap:

[austere crypt]

Better to Use rb Move function

[glacial forge]

any reason y?

[glacial forge]

this was dynamic btw i changed it kinematic to see if it would do anything

[rich adder]

ur player is kinematic

[glacial forge]

yup just comment on that its already back

[rich adder]

is this the only tilemap you have?

[glacial forge]

yes

[rich adder]

ahh your player is trigger

[glacial forge]

ah didnt realize trigger stops it from detecting

thought they both needed to be trigger

[rich adder]

OnCollisionEnter needs both solid , OnTriggerEnter 1 can be trigger and other solid as long its dynamic

[rich adder]

did you search in hierarchy t:EndTheTurn

[glacial forge]

ah ok makes sense

one more thing, what is the correct way to get the object form the collider? I thought i could just do an as but I cant so I'm not sure what is best practice

private void OnCollisionEnter2D(Collision2D other)
{
    Debug.Log(other.gameObject.tag.ToString());
    Vector3Int pos = new((int)other.gameObject.transform.position.x, (int)other.gameObject.transform.position.y, (int)other.gameObject.transform.position.z);
    (other.gameObject as Tilemap).SetTile(pos, null);
}

[wintry quarry]

no

GameObjects are never Tilemaps

Use GetComponent

Tilemap is a component on the GameObject

it is not the GameObject itself

[glacial forge]

ah i see

[wintry quarry]

also note that Collision2D is not the same as Collider2D

Collision2D is a struct that contains information about the collision.

[noble forum]

It works, the problem was that 'selectedcard' was null

[glacial forge]

so should i use the ontriggerenter function instead?

[wintry quarry]

Only if you're dealing with trigger colliders

[glacial forge]

is there any reason not to turn on trigger for the tilemap?

[wintry quarry]

Do you want it to be a trigger or a physical collider

If you want it to be a trigger, make it so

[glacial forge]

i cant say i know the difference other than it will trigger or not

[wintry quarry]

Triggers are not solid objects

they exist merely to facilitate OnTriggerEnter etc

objects will not physically collide with them

[glacial forge]

ah ok, well in this case it doesn't matter since its instantly destroyed when the player touches it so there are no physics to be done with it.

is a trigger collider easier on the computer then since its taken out of physics?

[wintry quarry]

but the player will be affected if it's a physical collider

it will bump into it

[rich adder]

colliders / triggers are still physics

[wintry quarry]

no triggers are not "easier on the computer"

[glacial forge]

better/worse performance was the wording i was looking for, but fair enough. essentially though its just a digging game where the player is falling down. Its gonna be fixed velocity down with a/d controls and blocks break as the player runs into them. so i dont care about physics since the rate of movement wont be changed by the world other than maybe changing the velocity by calculating what kind of tile is going through

if it doesn't make a difference on performance I will switch it to a trigger collider and just use on trigger enter

[glacial forge]

Perfect, got it all working. Thanks!

[ruby zephyr]

Guys, do you think it would be worth it to go through an online course that is paid to learn game development specifically in unity? Ignore the expenses.

[naive pawn]

paid
no

!learn

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[naive pawn]

the internet is full of free resources

you absolutely do not need paid courses

[ruby zephyr]

Let's talk about quality not accessibility

[glacial forge]

What is the correct way to implement global data in a game? This isnt just the settings menu where you change sound, im talking data alot of objects will look at and use for calculations/ some setting on how certain objects behave.

In my research i have seen 2 main methods and that is just make a static class which is what im familiar with outside of unity, or make a singleton script. Im not sure how to make a singleton script persist through scenes though so I dont know if that is relevant.

Just trying to learn best practice for future reference

[onyx cove]

Hi, I'm currently using the Meta Voice SDK and having issues, but I'm not sure why. Does anyone know why I'm getting these errors?

[grand snow]

static class will just work but not be a monobehaviour. a singleton mono can be kept alive through all scenes by using DontDestroyOnLoad() on it.

[glacial forge]

but how do create it the first time?

[naive pawn]

doesn't change the answer

the only difference in paid courses is that they're paid
there's not really a difference in quality

[grand snow]

have it in some scene or instantiate it manually via a prefab/manually. In its awake it can set a static field to this.
You can consider using the runtime initialize on load attribute to make it very early on https://docs.unity3d.com/6000.0/Documentation/ScriptReference/RuntimeInitializeOnLoadMethodAttribute.html

public static MyClass instance { get; private set;}

private void Awake()
{
  if(instance == null) instance = this;
  else Destroy(this);
}

[glacial forge]

it would contain data other objects would use in their start function. also my game transitions between scenes alot. so I was just thinking I didnt want to drag it into every scene/make an object for every scene because that seems bad. is there a reason to do it this way over a static class or is it just so you can use inspector on it?

[ruby zephyr]

How about a mentor? Would make a big difference?

[grand snow]

Its as you just said, it depends if it actually needs to be a monobehaviour or not. If you do not need serialized variables on it and the mono event functions then no need.
You can also consider a scriptable object but you would need to explicitly load it on game start to make it exist and then need some static field to access it too.

[naive pawn]

perhaps, but imo you don't really need that either

it'd maybe make a difference in the journey, but not in the result

if you have the persistence and willpower to put in effort, you can learn without a dedicated helper just fine
just gotta utilize the resources you have, and free resources are plentiful
if you ever have a specific question that you can't find answers online for, you can always ask here for free

[glacial forge]

i see so the main reason to do it thatway is for the mono event function. If im just using it as a global storage bin then static class is no different

its literally just holding values for other objects

thanks!

[naive pawn]

another point; having a mentor falls into a similar hole as trying to get direct/dm support; it's only one person. they won't always be free, and 2 eyes on a problem can easily miss subtle details. community support, like this server, gets around this by utilizing a whole community to see your issue and potentially point out causes (or even unrelated issues)

(and that's assuming a mentor is fully competant, sometimes inexperience in a specific topic can lead to misdiagnosing problems)

[ruby zephyr]

I don't really consider myself slow enough to not follow tutorials, maybe I'm just exaggerating. Do you think I just need time?

[glacial forge]

@ruby zephyr my 2 cents may not matter much here, but as someone who has tried making a game multiple times and failed I can assure you it has never been becasue i couldnt figure out how to do something. What killed most of my games was just passion/time. if you have infinite time and you actually want to make a game then there is plenty of free resources everywhere. There is tutorials for almost everything and unity manual/ this discord has gotten me the rest of the way. in my opinion the only thing paying for tutorials would have done for me is burned money

[naive pawn]

oh, everyone needs time.
gamedev is not a single skill, it's composed of many different aspects
graphics, programming, design, audio, and then weaving it all together.

programming itself isn't a single skill either; it's decomposing a problem, designing a solution, debugging, understanding errors, being able to research effectively

so it will take time and patience. maybe you might be underestimating how much it takes.
but if you have the will to practice those skills, you will get as far as you want. (there's not really an end to a journey of developing skills)

also, if you aren't confident you'll be able to develop those skills enough to be a game, don't worry about that
if you want to learn now, start learning! whatever you learn will be transferable to other situations or projects or whatever, and maybe you'll find the confidence as you build your knowledge and experience

[ruby zephyr]

That's enough to encourage me, thanks! I guess I'll just finish all tutorials in Unity Learn, try, and Improve.

[brave compass]

I would say paid courses or mentors can have an element that free resources do not, which is accountability. If you've given money to a person and there's an expectation that you will be somewhere at a time (physically or virtually), it's a push to keep going.

You don't need that push if you're super passionate and self driven to learn. But not everyone has that, and some elements of game dev can be boring to learn.

[naive pawn]

i mean, you can do that yourself with project planning

deviate from learning the actual gamedev for a sec to plan out your learning/development journey, set appropriate milestones

[brave compass]

The extreme end of that is university. It's pretty easy to give up on your own plans, but dropping out of school is a bigger deal.

[glacial forge]

the thing that i find is the most helpful is just getting excited about an idea. just make sure your first project is simple that you can do it quickly but still interesting enough that you want to pursue it. you can definitely just watch tutorials to watch tutorials, but having an idea first i find to be helpful so you can learn different examples and methods from tutorials. Of course I come from a strong programming background so if you dont have that foundation I would definitely work on that. just getting your first win always feels nice!

as to accountability im making a game with a friend this time so we are keeping each other accountable but like listed above there are a few ways to do that.

[naive pawn]

wait i just noticed you said "all tutorials" lol
unity learn is really vast, and most likely they won't all pertain to what you want to make
choose the courses relevant to what you want to make

[ruby zephyr]

So what should I really stick to learning?

I was told to learn programming of c#, learn Unity hub's environmental, (tools, stuffs inside), and try to apply in game development

Currently I'm only learning basic c# and could not apply it to unity

[naive pawn]

learn about stuff relevant to your goal

if you don't know how to code, then yeah some basic c# before going to unity c# would be nice
there are also some resources pinned in this channel

[ruby zephyr]

Really?, like what, if I want a shooter game should I not learn how to make a horror game as well?

Lets say, I want to make a variety of Indie games

[naive pawn]

well, if you want a shooter game, you wouldn't need to learn about, say, dynamic audio cues

it's not like learning is a one-time thing

focus on your current goal

if you want to make a horror game, learn about that
if you want to make a shooter game, learn about that

[brazen crescent]

I'd advise to look at ScriptableObjects as well

[ruby zephyr]

If I want to make different genre of games, I would then have to start, learning about the most basic one like for example platformer and then proceed to the next level?

[naive pawn]

i mean you wouldn't be learning about how to make a shooter game
you would be learning, say, first-person controls, basic inventory systems, HUDs, physics, modelling, sound effects
a lot of that would be applicable to a horror game too
but some wouldn't, like reloading mechanics. unless you can shoot the monster, idk.
and some skills would be more specific to horror games, like playing with dim lighting, or elaborate animations or cutscenes, or writing a story

if you're currently making a shooter game that doesn't have those elements, then no need to learn them yet

[naive pawn]

well, like above, you'd learn basic mechanics, and those basic mechanics can be made into a basic game
then you would have more complex mechanics, or multiple basic mechanics, that you can combine into a more complex game
etc

you don't need to make a game for each step

as you learn more, you'll be able to make more complex mechanics/games

[ruby zephyr]

Here's what I wanna do:

When you told me to learn the things that I just want, but then I wanna develop different genres as well which would mean I have to learn different mechanics,

I had a plan of learning the easiest components of games like,

• I'lll make a button to play,
• simple wasd movement
• and other more

So for every game I'd have to learn how to make something that they all have in common?

Then I'll learn how to make a character, make it move, and interact. Because this applies to many games.

_

I have actually never thought of that idea.

[trail heart]

@ruby zephyr Even if there's nothing in paid learning resources that isn't out there in free tutorials, they're generally better in my opinion
Unlike scattered free tutorials they can be connected and cohesive learning paths that ramp up the complexity gradually over many projects
They also serve as examples and pre-compiled notes for you later
But since anyone can just start making and selling courses their quality also varies a lot, so it's best to research their offering and reviews before committing

[zenith mantle]

it keeps increasing if im not looking at an interactable

[frosty hound]

Line 27 of your PlayerInteract script is trying to reference something that doesn't exist.

A good guess is that you're trying to do something with the object the player is looking at, which doesn't exist if they aren't looking at something.

[wintry quarry]

Yep, gotta make sure when you Raycast your code is actually checking for a valid hit or not

[zenith mantle]

so uhm what

also gotta say im just following a tutorial so uh ye

thanks in advance if yall reply 🙏

[wintry quarry]

You have a semicolon where it doesn't belong

There's a reason it's underlined in a green squiggle

[zenith mantle]

after the distance))?

[wintry quarry]

It's trying to warn you

[zenith mantle]

ohhh

[wintry quarry]

Yes

[zenith mantle]

hm how about this ?

or is it always like that even when im not jumping

[wintry quarry]

Don't you see the line that explicitly sets it to -2 ?

[naive pawn]

there are several free, high-quality courses that aren't just single feature guides
and single feature guides can also be more helpful in some cases as well

courses may be better depending on your learning style, sure, but there's still no difference between a paid course and a free one aside from spending money (and the commitment that comes with that)

[zenith mantle]

i do

actually

nvm i just remembered this exists

[trail heart]

There's so many resources out there it's hard to generalize
There's high quality free stuff and low quality paid stuff, but on average the balance goes the other way
Ideally when paying you get access to support or teaching assistants as well
I don't recommend everyone to buy courses outright, and hunting for bundles and sales is much better than ever paying full price, but if the premise is that money is no issue then there's not really a drawback to taking that shortcut

[zenith mantle]

is anything wrong

its not weaponswaying for me

[slender nymph]

double check the axes you are getting input from

[zenith mantle]

which

[slender nymph]

read your code and find out!

[zenith mantle]

aa

ok

time to fuck around and find out

[slender nymph]

do you just not know what an axis is? or that axes is the plural of axis?

[zenith mantle]

i just got confused

ok but i know its a plural

[frail hawk]

how about reading some unity docs?

[polar acorn]

Do you get any messages in the console

[frail hawk]

and this

[zenith mantle]

holy

[slender nymph]

crazy how actually paying attention to error messages can help you fix issues

[zenith mantle]

honest stupid mistake i swear

another stupido question what am i supposed to change

also my excuse is

i just got unity

today

[verbal dome]

It literally tells you

[polar acorn]

Well, do you want to use your own custom axis, or one of the ones unity provides?

[slender nymph]

finish a thought before sending a message. and consider going through the pathways on the unity !learn site to actually learn how to use the engine instead of trying to skip ahead to a finished product

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[zenith mantle]

unity provided

[polar acorn]

So you might want to look up the names of those

And use the ones that actually exist

[rancid tinsel]

is the component pattern just... adding components? it seems so simple, so much so that it doesnt sound right

[polar acorn]

Yes. It's more complicated when you're not using Unity

It's a general programming practice that Unity was built around

[wintry quarry]

it's the whole setup of having containers (GameObjects) and adding behavior to them with components

[rancid tinsel]

ah okay that explains it

[polar acorn]

Yeah, it seems easy because Unity was designed to make it easy

[rancid tinsel]

wait so whats the difference between that and decorator

is decorator at runtime?

[polar acorn]

It seems like it's mostly just a difference in mindset - whether you're adding functionality to a neutral container, or putting neutral data into a functional container?

[rancid tinsel]

ah so its about intent i guess?

adding a rigidbody to a player would be component, but adding a playercontroller script would be decorator?

[polar acorn]

Seems like it? I dunno, I'd need to see some more concrete examples of a decorator pattern to really grok it

[queen adder]

This Code should work but is there a more elegant way? My intuition thinks this should be possible without creating a int count variable

                        //Check is all Quest cleared
                        
                        //Count how many are finished 
                        int questCleard = 0;
                        for (int j = 0; j < _quest.Length; j++)
                        {
                            if (_quest[i]._questCout == 0)
                            {
                                questCleard++;
                            }
                        }
                        //All Clear?
                        if (questCleard >= _quest.Length)
                        {
                            TransformMotherCell();
                        }
                        

[slender nymph]

you can use a linq method for that, like .All

[polar acorn]

So you need to check if they're all cleared? You could also check if any of them are not cleared, and if they aren't, exit early.

[slender nymph]

or that

[polar acorn]

If the code reaches the end of the loop, they're all cleared

[queen adder]

That's a good idea

[grand snow]

I often do that, where if you require everything to meet some criteria you return early if any are false.
then after the loop you know the condition was met.
